Does this software use Qt's PDF tool for its PDF reading function? based on Poppler or muPDF? I ask this because when I opened a 600MB PDF file, I found its perfemance is not very much.

Thanks for getting in touch and asking about the PDF reading tool used in my software.

I want to clarify that my software doesn't use Qt's PDF tool, and it's not based on Poppler or muPDF for its PDF reading function. Instead, I created a proprietary implementation for processing PDF files in my software.

To give you a bit more insight, this implementation may require more memory due to its multi-threaded nature. In addition, I also use a cache for page images, which might further increase the memory usage. Although this might require a bit more memory, it allows me to enhance the performance and efficiency of my software.

I apologize if you experienced any inconvenience while handling a large PDF file with my software. Your feedback is valuable, and I always aim to improve. Could you please provide the file?

If you have any more questions or need further clarification, don't hesitate to contact me.

Best Regards,

The PDF is too large to upload, you can download it in https://www.yxftp.com/%E5%BD%B1%E5%83%8F%E7%94%B5%E5%AD%90%E4%B9%A6/%E5%BD%B1%E5%83%8F%E7%BB%BC%E5%90%88%E7%94%B5%E5%AD%90%E4%B9%A6/%E8%82%BF%E7%98%A4%E5%BD%B1%E5%83%8F%E8%AF%8A%E6%96%AD%E5%9B%BE%E8%B0%B1%EF%BC%88%E5%91%A8%E7%BA%AF%E6%AD%A6%EF%BC%8C%E4%BA%BA%E6%B0%91%E6%96%87%E5%AD%A6%E5%87%BA%E7%89%88%E7%A4%BE%EF%BC%89.pdf

Hello, the program uses cached data, so cache causes huge memory consumption. However, there was a problem, that thumbnails were recompiled again and again, I have fixed it. Please try it.
